Animation Nodes: How to hiccup letters individually?
The first effect can be achieved very similarly to my answer here. The inverse of a delay falloff is used to offset the matrices of each of the characters by scaling them to zero and moving them in the negative y direction:



The second effect can be achieved by introducing a rotation to each character. The rotation of each character will linearly depend on its index, where the rotation of the first character is some negative scalar and the rotation of the last character is some positive scalar:



The third effect can be achieved by introducing a linear offset along the x axis based on the index of the characters, this is done similar to the second effect as follows:
